Do you have a broker?

[tyrim88]

A broker is required to make investments such as stock purchases and sales. Brokers have a special licence that allows them to trade on stock exchanges. You can choose between a full-service broker and a discount broker depending on how much service and help you want from your broker.

That is true about the stock exchange market,in the market and trading on the floor,you cannot just enter and start trading,you will need the services of a licence brooker to do you sales and buying for you.
